Shopping alert March 17, 2011 8:29 am Last night at La Grenouille, Federico Marchetti, CEO and Founder of YOOX Group, and Kenneth Jay Lane, celebrated their new collaboration, on a range of costume jewels exclusive to the e-tail megalith. Dinner was just a small gathering of friends and editors—though, of course, when you’ve been in the bauble biz as long as Lane has, you have quite a few friends, including the fabulous likes of Iris Apfel. Starting this week, you’ll not only be able to find KJL’s collaborative pieces on Yoox, you’ll also be able get some of his unique vintage and classic styles. That said, the new pieces are the ones that caught my eye, like these chain-link necklaces. Retailers far and wide are into collaborations, but this meeting of Europe and the U.S. was particularly good. So it’s welcome news that the Milan-based Marchetti just bought an apartment in town and is planning on spending more time here. With any luck, that means more American designers will be on his radar for further collabs to come.
